SADIRON.

riginal No. 1,549,957, dated August 11, 1925, Serial No. 697,930, iiled March l8, 1924, Application for reissue iiled December 9, 1926. Serial No. 153,711.`

This invention relates to sad-irons such as are used. in tailor shops and clothing manufactures for the pressing of garments, and more particularly to the-class of 1rons which 5 have incorporated therein -a heating element, a water vaporizing chamber, and l ports ada ted to'discharge vthe vapor generated 1n sai chamber through the working face of the iron onto the goods.

The object of this invention 1s to improve the construction and operation of such irons by providing means whereby the water vapor delivered to the usual discharge ports may be controlled and quickly varied atwill.

ject is illustrated in the accompanying rawings, in'which y Fig. l is a plan View of my improved iron,

Fig. 2 is a side elevation,

Fig.' 3 a cross section along the line :v on Fig. 1, and i Fig. 4 is a detail plan view of the shutter M and its actuating mechanism.

The same reference characters refer to the same parts throughout the several vlews.

In the drawings, A represents the base or shoe ofthe iron, C the shell 'like cover or combustion chamber, B a burner mounted therein, D a guard plate or deliector, and E y the handle.

Formed in the base A is a horizontal longitudinal water vaporizing chamber F, adapted to receive water in suitable quantitles delivered through a pipe f preferably proyvided with an inlet valve f adapted to be connected by a suitable exible connection, as, for instance, by a rubber tube, to a source of supply. When the iron is in use the base becomes heated, due to the action of the heating element here villustrated as a usual type of gas burner, and water admitted in proper quantities to the chamber F- will be vaporized b heated meta A cross port G connects the forward end of the chamber F witha longitudinal horizontal distributing chamber which is rovided with a number of'outlets Aor ports g, J, opening through the bottom or Working face of the iron.

In so far as I have now described my imroved iron it does not differ materially rom similar irons nowon the market, but

in these irons the amount of water vapor delivered to the orts J, 'J, can be controlled only by manip ation of the inlet valve.

The manner in which I accomplish m ob c t dehvery of vapor will cease, and that it is coming into contact with the rarily, and with the present types of irons ao l.this is not a simple matter, especially when the variation in the icw or the stoppage thereof is to be made quickly and for a short time only. In practice it has been found that the adjustment of the inlet valve so as to give the most satisfactory volume of vapor, is a delicate operation due to the' limited amount of Water which is normally required; that after the valve is closed there is an appreciable lapse of time before the impracticable to temporarily vary the amount of vapor delivered by adjusting the in'let valve. i l

The particular object of this invention is 75 to overcome the deficiencies in the present e types of such irons by providing means whereby the amount of water vapor delivered tothe distributing chamber may be 'easily and quickly varied, or entirely cut oil' 80 .without disturbing in any Way the w of .v

water to the vaporizing chamber, or`in any lway'disturbing the rate at which' the same will be vaporized. A v

In my improved iron, illustrated, the cross port G, connecting the vaporizng chamber F to the distributing'chamber H lies at a higher level than that of the chambers F 'l and H.

In the model illustrated the port G lies no entirely outside of or above-the base A, being formed in a fitting attached to the body and,

extended as at K so as to :formA an outletI Lopen to atmosphere. Those parts of the ports which are in this model formed in a tting attached to the body proper may be formed inl the body proper if so desired.` Pivotally mounted at some suitable point, as at N, is a swinging shutterJM, ada ted to close the port L but preferably norma ly held in open position by `means of a` spring S. Convenient means are provided whereby the shutter M may be easily and quickly swung into closed position simply by pressure of the operators thumb upon a conveniently located handle or lever.. These means are here illustrated asa conveniently locatedY handley P, fastened on a vertical shaft R, near the bottom of which is fastened a tongue or arm T, adapted to contact wit-h the arm m of the vertical port ber H and out of` the ports J J.

shutter M, so as to actuat'e the shutter and close it against the tension of the s ring S. Refer now to Fig. 3. It is a well) known fact that water vapor tends to rise, and while the port L is open the vapor generated in the chamber F will naturally rise through of theK port and the extension` g discharged. throughA the port L into atmosphere. If now the shutter M is actuated'to close the port L, the vapor not bein able ,to esca vertlcal port g3, into the distribntin chamy Pal" tially closing the port L, as y not firmly vseating the shutter M, a part of the vapor maybe allowed to escape at that point and a part only be forced into the chamber H. This may also be accomplshed by. `intermittently opening and closing the shutter. The

orts gz'and g3 together with the cross portprovide a water-flow ch cking means, which permits the vapors to freely pass to the distributing chamber but which restrains the ow of water to the distributing chamber. f

' mittin The proper adjustment of the inlet valve f having once been accomplished, the portion of the vapor generated w ich is to be delivered through the ports J may be regulated b simply pressing on the handle P, so as to cibse, or only partly close the shutter M.
